To John Strain:
You mentioned that Nikon might not be able to make a full frame sensor in their cameras because of the small lens throat. This should not be true since same lenses are used also on film cameras with 24x36mm format? Or am I wrong? (sorry I am not a Nikon user).
On the other hand I understand Nikon claimed they will stick to a format with form-factor of 1,5. Interestening to see if Nikon will maintain this claim with the arrival of EOS 5D and, as I heard, EOS 50D soon, both with full format sensors.
So, my question: the real reason for Nikon's claim to stick to 1,5-form-factor format is made because of their lenses?
